What harm can too much UV light exposure cause during gel extraction?

Answer and explanation

Correct answer: DNA can be damaged or thymine dimers may form

UV light can damage DNA bases and may form photoproducts such as thymine dimers. This can reduce the efficiency of downstream procedures such as PCR, ligation, or transformation. Option B is incorrect because UV exposure does not improve DNA purity; it can reduce DNA quality. Exam tip: during gel extraction, visualize the DNA band for the shortest possible time under UV light and excise it quickly; a blue-light transilluminator is preferable when available.
